No actually you can keep the IHS, and use it as part of the block. The o-ring is just an added safety, for leaks, because you never know how the actual geometry of the IHS is going to turn out.
In fact having the IHS already gives you a small advantage, because you have a protective layer on top of the core.
If anything, because of the TIM joint to the fins, you'd have to compensate by making the gaps between the dimples, a bit smaller: because the TIM joint is going to cause the heat to accumulate within itself, you only need a very thin wall between the dimples.
The hardest problems really, is getting the nickel plating off of the IHS, and lining up those dimples as tightly as you possibly can.
